Well, yeah. The sovereign state of South Carolina, through an act of her legislature, did "...cede to the United States, all the right, title and claim of South Carolina to the site of Fort Sumter and the requisite quantity of adjacent territory..." So having relinquished all claims to Sumter, what rule of law gave them the power to say, "Hey, just kidding. It's really ours?"
But even though they had sovereignty they still offered to pay for it.
If true, then shouldn't they have paid before taking control? And if the owners said "not interested" then what gave them the power to just take it?
Btw Cuba still maintains sovereignty over gitmo.
That wasn't my question, but even so by your definitions of sovereignty then Cuba has a right to just take Gitmo back at any time, right? By force if necessary? And you would say they were legally in the right?
Thanks, that's a key point.
Is there a source I could link to?
